TOILET VENT ILATING APPARATUS Filed Oct. 1, 1965 FIG 4 INVENTOR WALTERSCHULZ 5 a ATTORNEY TOILET VENTILATING APPARATUS Walter Schulz, 134Westmount Ave., Toronto 10, Ontario, Canada Filed Oct. 1, 1965, Ser. No.491,913 1 Claim. (Cl. 4-217) ABSTRACT OF THE DISCLOSURE This inventionrelates to improvement in toilet ventilating apparatus.

It is conventional practice to provide ventilation for washroom and thelike by means of an evacuation fan generally placed in the ceiling ofthe room. The chief disadvantage of this method of ventilation is that alarge volume of air must be moved in order to fully ventilate the roomand toilet bowl so that removal of odour is a relatively time-consumingprocess. Furthermore, contaminated air is caused to move oversubstantially the whole of the room before being vented.

Various means have also been proposed for withdrawing foul air from thetoilet bowl and discharging same into the outside atmosphere by suctioncreated in pipes leading from the interior of the bowl. Such means have,however, in the main have involved extensive constructional departuresfrom the conventional type of bowl, which have greatly added to the costof the equipment and to the bulk and in most cases have notsatisfactorily accomplished the object for which they were intended.

The main object of my invention is, therefore, to provide toiletventilating apparatus which will remove air direct from the interior ofthe toilet bowl instantly and expel same directly into the outsideatmosphere.

A further object of the instant invention is to provide ventilatingequipment which may be fitted to any conventional toilet in the samemanner as the normal seat.

Still a further object of my invention is to provide toilet ventilatingapparatus which will also adequately ventilate any room, such as abathroom, in which it is located.

I achieve these and other objects and features by providing a channeledtoilet seat hinged to the forward end of an air collector chamber and sorelated thereto that when the seat is in its seating position thechanneled portion thereof is in register with the inlet to said aircollector chamber. The air collector chamber in turn is connectedthrough suitable duct work to the inlet side of an exhaust fan whichthen evacuates the air to outside atmosphere.

And generally the objects of the invention are to provide toiletventilating apparatus which will be efiicient in operation, of simpleconstruction readily adaptable to a great many known types of bowls, andwhich can be produced at reasonable cost.

With the above and other objects in view the invention consists in thenovel features of construction, arrangements and combinations of partset out herein and shown and more particularly pointed out in the claimfor novelty which follows.

In drawings which illustrate the presently preferred embodiments of theinvention:

FIGURE 1 is a part cut-away perspective view of a toilet embodying thefeatures of the present invention, shown attached to a conventionaltoilet bowl,

FIGURE 2 is a sectional side elevational of the rear part of the toiletseat of FIGURE 1, taken on the line 2 FIGURE 3 is a perspective view ofthe undersurface of the seat portion of the invention, and

FIGURE 4 is a diagrammatic sketch of the general layout of theventilation system incorporating the ventilating features of the presentinvention.

Referring to FIGURES 1 and 2, a toilet ventilating assembly 1 include anair collector chamber 2, a toilet seat 3 and a lid 4. The air collectorchamber 2 extends across the bowl comprises a bottom wall 5 supportingside.

walls 6 and 7 at the ends thereof and enclosed at the top by an upperwall 8. The side walls 6 and 7 are of substan tially quadrantalconfiguration with their vertical edges 9 and 10 respectively being atthe front of the chamber 2, and their upper edges 11 and 12 respectivelybeing arcuate. The upper wall 8 is also arcuate in section in order tofollow the contour of the upper edge 11 and 12 of the side walls 6 and7.

The front of the chamber 2 is open with the exception of a low flange 13extending upwardly from and over the full length of the front edge ofthe bottom wall 5.

The material forming the upper wall 8 is of increased thickness at thefront edge thereof as indicated at 14 and a pair of cylindrical holes 15are formed, therein, one at each side, to accommodate hinge pins 16. Thecut-aways 17 formed in the front edge 14 accept the hinge portions 18 ofthe seat 3 and the hinge portions 19 of the lid 4.

The bottom wall 5 of the chamber 2 is adapted to extend transverselyacross the rear of a conventional toilet bowl 20 and to be attachedthereto in the same manner as a conventional toilet seat by means of apair of bolts 21, the wall 5 being suitably perforated to permit thebolts 21 to line up with the holes provided in the toilet bowl 20.

The side walls 6 and 7 extend downwardly and rearwardly to act as sidewalls for a pair of outlet boxes 22 and 23 respectively which areextensions of the air collector chamber 2. The outlet boxes 22 and 23are located at opposite sides of the device and are sufiiciently spacedapart to permit them to be assembled on each side of the base of thetank 24 generally utilized to supply water to the toilet bowl 20. Outletpipes 25 and 26 extend rear- Wardly rom the outlet boxe 22 and 23respectively and, as illustrated particularly in FIGURE 4, these outletpipes are adapted to connect with the inlet side of an exhaust fan 27,the outlet duct 28 of which is led to the exterior of the building underthe hood as shown at 2.9.

Referring to FIGURES 2 and 3, the toilet seat 3 is of substantiallyconventional shape in plan but is substantially arcuate in ection,partly enclosed at its rearmost half by a base portion 30. The baseportion 30 includes two oppositely located side strips 31 and 32extending rearwardly and inwardly from locations substantially half wayalong the side of the seat and connected at the rear of the seat by atransverse strip 33. With the seat 3 in a horizontal position, the baseportion 30 is also in a horizontal plane.

A plurality of vertical direction vanes 34 extend between the baseportion 30 and the underside of the seat 3 in a generally longitudinaldirection. As previously described, the seat 3 is hingedly attached tothe chamber 2 by hinge portions 18, and, as in conventional toiletseats, resilient stops 35 are attached to the lower edge 36 of the seatto contact the toilet bowl 20 and at the same time ensure a space ismaintained between the upper edge of the bowl 20 and the lower edge 36of the toilet seat 3.

The lid 4 is of conventional design and is also hinged to the chamber 2by means of its hinges 19 as described. Resilient stops 37 on theunderside of the lid 4 are adapted to contact the seat 3 when the lid isclosed and in this mannera gap 38 .is maintained between the lid and thetoilet seat when the lid is closed down.

In operation, upon activating the exhaust fan 27, air is caused to flowfrom the washroom or the like into the upper end of the toilet bowl 20between the gaps existing between the seat and the bowl and the seat andthe lid as described. This air, together with air from the toilet bowlis then directed by the directional vanes 34 through the collectorchamber -2 in substantially equal amounts to the outlet boxes 22 and 23.From the outlet boxes the outlet pipes 25 and 26duct the .air to theexhaustfan 27 which then expels it to atmosphere through the outlet duct28 and the hood 29.

From the foregoing, the construction and operation of the invention willbe readily understood and further explanation is believed to beunnecessary. However, since numerous modifications and changes willreadily occur to those skilled in the art, it is not desired to limitthe invention to the exact construction shown and described, andaccordingly all suitable modifications and equivalents may be resortedto, falling within the scope of the appended claim.
